| Abstract: | Hemispherical resonator gyroscope(HRG)is a novel kind of solid-state gyroscope that measures angular velocity through Coriolis effect. The advantages of simple structure, high precision, low power, long lifetime, high reliability and radiation robustness make HRG the most suitable sensor for strap-down inertial navigation system especially for space applications. Not-limited by quantum effect, HRG is regarded as an important path to high-precision miniaturized gyroscopes. This paper first introduces the basic principles of HRG, followed by its development history and current advances. In the end, the future trends of HRG technology are discussed |
